larly to provide improvements in machinesI of the character set forth inU.` S. Patent N o. 1,303,837, issued to Wyckoff and Handschiegl,l on May13,1919, or machines adapted tol carry out the process set forth in thatpatent or in Patent No. 1,303,836, issued to Wyckoff and Handschiegl, onMay 13, 1919. In machines of this general character the films haveheretofore been moved by the member (preferably the drumlor the like) onwhich they are carried when in pressure contact, or the are pulled -overor around the member (t e drum) on which they are carried in pressurecontact. In either case,

before the films are brought into pressure contact on the drum they areulled through or over a mechanism, designed) sion on them. vThe means,by which the films have heretofore been kept tight, or by which theyhave been kept under tension before coming in contact with each other,have embodied various arrangements o rollers provided with frictionl orNbrake means. It has been found in practice that such arrangements for.keeping tension on the film are-not satisfactory in that the `films donot keep in accurate register, do

not feel evenly and oftentimesI kink. In the machine provided by thepresent invention the films are kept tight by driven rollers which areso provided with resilient friction or brake means as to compensate forshrinking or difference in lengths of films and at the same time keepevenl tension onthe films being fed 'into pressure contact.

There are other objects and features of the invention which will be bestunderstood from. the following detailed description of apreferredembodiment of the invention throughout which reference is had to theaccompanying draw-ings, in Which- Fig. 1 a front .elevation of themachine;A

prising uprights 11 and 12 which extend 'upwardly from a common base 13and are connected near their upper ends by cross .member .1 4. The mainframe 10 is preferably cast and its various parts are preferablyintegral. I

A horizontal shaft 15 is carried in bearings 16 and 17 in the uprightframe inembers l1 and 12, respectively. The shaft 15 extends beyond the'u right 11 and has mounted on its exten ing portion a filmdrum 20. vThefilm carrying drum carrying 20 is the member on which the films 21 and22 are brought into pressure contact. The drum 20comprises a rim 29supported from edges of face 23 of drum' 2O there are sprocket teeth 24which are spaced and proportioned to engage the perforations 25 instandard motion picture films. The engagement of the film 25 by theteeth 24 prevents slipping or moving of the films after they have beenbrought into engagement with the drum 2O and with each other. In orderto facilitate checking up or examining. the

films, when they are in pressure contact,vto

see if they are in proper register, transparent panels 26, preferablyglass, are provided in the rim 29 between the spokes 27. The panels 26can be mounted or carried in the rim 29 in any suitable manner; forinstance, as shown .in the drawings, they may be beveled and, set inconical openings and a beading 30, which fits a vroove 31, maybeprovided behind them. llhe drum 2O 1s kept spaced the proper distancefrom the upright 11 byi the inner edge of hub ber 11.

moving away-from the upright member 11v by hub 34, of worm wheel 35,engaging the inner end ofthe bearing 16, as clearly shown in Fig. 2.

The drum 20 is driven in the direction 'indicated by the arrow. in Fig.1, by worm gear 36 meshing with worm wheel 35 which is tight on shaft115.. Y'llh'e worm `36 isf mounted on and driven by a shaft 37 carriedin suitable bearings 38. The shaft 37 has mounted on it a` gear 40driven by a gear 41 mounted on the main shaft 39 .carried in bearings 41as shown in Fig. 6. The ends of the shaft 39 are provided with suitableiianges 42 by which the machine may be connected with other machines ormechanisms or by which .the machine may be connected to a drivingmechanism such as a motor, engine, or the like.

A clutch mechanism 43 is provided between the main drive shaft 39 andthe Shaft 37 so that the machine. can be thrown out of operation withoutstopping or disconnecting the main drive shaft 39. The clutch mechanism43 comprises a slider 45 which has clutch jaws 46 and which is splinedor slidably keyed by meansof key 47 to the shaft 39. The spur gear 41 isfree on the shaft 39 and is provided witha hub 48 in which are cutclutch jaws 49 adapted `to co-operate with 'clutch jaws 46. It will bereadily .understood how the jaws 46 and 49' are moved in or out ofengagement by moving member toward or away from the gear 41, and

v that the gear 41 is only driven when the jaws 46 and 49 are inengagement. Any suitable mechanism may be arranged for shifting ormoving the' member 45, for linstance, a rod 50 may be slidably carriedinthe frame 10 so as to be parallel with the shaft 39 as shown in Fig. 6.The rod tlmay be moved manually or by a lever arrangement and -a sleeve51-,having a finger 52, may be mounted on the rod 50 so that the finger52 engages anannular groove 53l in the slider and thereby causesmovement of the slider 45 when the rod 50 is moved.

The driving arrangement just .described makes it possible to connectseveral lnachines or units and drive them synchronously and at the sametime b e able to disconnect or fering with the other machines.

The color carrying negative film or`the film which carries the materialsto be transferred to the uncolored or ositive film is carried'on a spool6 0 and is ed to the drum 2O so that its Acolor carrying face is out.The

spool 6F and the mechanism through which the film 22 passes or runsbefore 1t engages the drum 20 is carried by a U-shaped rame 61 which iscarried between the uprights 11 which the film is fed onto the drum 20.4roller 80 is mounted on and driven by a st op any'particular machinewithout interwhich arm is adjacent to the upright 11,l and has' a shortarm 65v extending upward from the end of the'base 63,I which arm isadjacent to the upright 12.. The short arm 65 is connected with theupright 12 by an y.adjusting mechanism 66 Whichwill be hereinafterdescribed. The nspool 60 is revolubly mounted at the top end'of the arm64 andk is mounted on the side ofthe arm 64 which will cause it to be inline with the drum 20. The color carrying film 22 upon leaving the spool60 passes around a friction or drag j sprocket or roller 6 mounted onprojection. 68which extends f omthe arm v64, as clearly.

/shown in Fig. 1. 'The spindle 69 which'carries the roller 67 extendslfrom the projection 68and has, lscrew threaded on itsouter end,

a knurled nut 70. A shoulder a on the spindle 69 spares the roller 67from the arm and allowsthe spindle to be' lockediirmly on the armby nut70". A' resilient washer 71, preferably rubber, is carried on thespindle 69 between the outer end of the roller 67 and the inner end ofthe knurled nut 70. The knurled nut 7 0 is screwed onto the spindle` 69until the roller 67 is pressed or held against the shoulder 7()a withsuflicient pressure to cause the desired amount of friction or drag. Thefriction on the roller 67 is preferably just suiiicient to make itnecessary to draw or pull 'the film around it and is suiiicient toprevent it frombeing rotated or carried around by inertia. The lilm isprevented from slipping on the roller 67 by sprocket teeth 74, similarto teeth 24,0n the drum 20, and the film is guided onto the roller 67 byan idler roller 75. The roller is carried on a shaft 76 which isadjustably carried in a slot 77 and is locked in the desired position bya nut 78. The roller 75 presses the film .against the roller 67 and theteeth 74-which extend from the roller prevent the filml from beingpulled or dragged around the roller without rotating it.

The lilm 22 after passing Aaround -theroller 67, as shown in Fig. 1vengages and passes around a drum or roller 80. The roller 8() is adriven member and is the member from The shown in'Fig. 8.

The shaft 81 is driven -through a friction mechanism from a gear mountedon shaft 91. Thegear 90 engages and drives afgear 92 which'is freelymounted on .shaft 81. A cylindrical casing-93 extends from the endva cap94;. A helical spring 95 extends between ashoulder 96, formed inthe-'cap 94,

and a ringj96fwhich is tightly keyed ontovthe shaft 81. The ring 96has arecess 97v into which the spring extends and afriction 4washer 98,preferably leather, isinterposed between the spring and the 'ri`ng," as

clearly shown in Fig. 5. Itl will readily understood howthe shaft 81 isdriven from g. gear 92 -through the spring and rin and that the pull ordrag exerted on the v by the roller 80, is 'dependent upontheadjustmentor! ressure put upon the spring 95.

This particular-connection not 'only providesv afriction joint orconnection `which may slip 'on application of sufficient pull on theroller .80 butalso provides a. resilient connection (dueto the spring95) which prevents. sudden slipping or jerking of the va.

The gear ratios throug out theentire mechanism hereincause the drum 2 0 to have a peripheral speed:slightly faster than that of the roller 80. This dii'erence'inspeedtogether with the resllient friction-drive provided by the.mechanism hereinabove. described will cause the film 22 to be keptunder an even tension between the drum 20'a`nd the roller;80 ,and

revents kinking or accumulation of film etween the roller 80 and thedrum 20.

Such la difference in `peri heral speed of, l lher with the 'ad-`justment of spring 95 'will b e .preferably drum 20 and roller 80 togetsuch as to cause the roller 80 -to drag or pull the. film 22 from thespool 60 around the roller 67 at the same time causing sufficient' pullltov come upon the between roller 80 and drum 20 to-cause a continualslippage in the drive mechanism of roller 80.

Gear '1417 is connectedbfy frictionmeansfwith `90 the shaft 116 in the same manner 'asl the gear 4 92 isconnected with the shaft 81;. lThe roller 115 performs -the sameyfunction 'and has the same action on film A21 as-the roller'SO hasvon'the'` film 22, that is, it dra-'gs or ulls, the -95 '.lm yinto themachine around the rag pulbringing together of the films causes trans- Ifer of color from` the negative 22 tothe positive 21.- It will-be.understood that this invention isl not limited in anyv way-to thelmanme'i`-` in which the negative film 22 is col-v ored or to anychemicaltreatmentjgivento the films prior to or after passing. throughthe machine. The machine,'however,;is .parftieularly` ada ted tohandlefilmsthathavebeen ehemica ly orotherwise as it will efficientlyhandle films that have'ibeen 11 5v stretched or shrunk. vThe amount oftension on the outer or'positive film governs the contact pressu'rebetween the two films; the difference intensions on-the two films'(which difference isregulated bythe -rop'er -120 rivmgadjustment -,ofthe two yielding means of rollers 80 and 115) causes di'ferentialstretching' of the twofiln 1s, which maythus be brought toregisterinclengms as set out in Athe patents before referred to. *122.The. amount oficolor transferred from negative l22 to positive 21isfdependent u on, amo other things. the pressure with w ch the ms are,held vtogether andthe time that they are in contact., It will .beunderstood 130 that the Acolor to be transferred and the por tion of thepositive to be colored do not enter into or concern this invention butare dependent upon the color carried by negative' 22 and the location ofthe color on the negative." In order to assure perfect contact be. tweenthe two films and to prevent sl1ght` kinking-or separation of the filmswhile they are on the drum a rubber roller 120 is mounted on an arm 121so as to engage the outer face of the outer film 21 just after it isbrought into contact with the' film 22. The arm 121'is mountedon a shaft170 carriedby the frame 10 so that-roller 120 is kept against the'ilmsby a spring 122 connected to an arm-171 which is also mounted on theshaft 170 as shown in Fig. 9.' The spring 122 is adjustable by beingattached to a plate 175 which is adjustably attached to the frame 10 at176. The pressure with which the roller 120 engages filml21 can beregulated by adjusting plate 17 5. The action of this roller iis toSqueeze'the' films ,togetherA into, uniform. contact, squeezing'out allair between them. --The .roller 120 can be lifted away from -the filmsby handle 123 which extends from the arm 121, as shown in F ig.

1, and it can be lifted so as to stay in the up speed a little greaterthan that of the drum 20. The rollers 125 and126 being driven in ditthis manner causea constant p ull or tension to be vkept -upon thefilms21V and 22 while they are in engagement on the drum; 20 and due to theirbeing driven by a spring belt they are not positively driven but ma beslipped relative tothe belt sufficient to hee them at the proper speed.-The rollers 125 and 126 are .of the same construction and mounting, eachbeing mounted on a spindle 129 and each having a pulley 130 formed atits inner end. The spring belt 128 which runs over the pulleys 130 runsover and is driven by a pulle 1 31which isfpivotally mounted on a spinle 132 extending from the arm-32. The pulley 131 is driven from a gear133 mounted bn the hub of the drum l20 gear 134 whichso as to engage anddrive is .mounted on the hub 135gof pulley 131.
